WHEEL-FLANGE LUBRICATOR.

T0 all whom t may concern.'

Be it known that I, TIMOTHY J. VVHOLEY, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful. lVheel-Flange Lubricator, of which the following is a specification.

vl'v invention consists of a wheel-fiange lubricator of the type disclo-sed in Letters Patent, No. 990,034, dated April 18, 1911, and No. 1,039,650, dated Se tember 2/1, 1912, both granted to Philip onniff, and particularly of improved means for retaining' the cap closing the rear end of the lubricant box or holder.

lt further consists of improved means for holding the rear end of the feeding spring.

lt further consist-s of other novel features of construction, all as will be hereinafter fully set forth.

The annexed drawings and the following description set forth in detail one mechanical forni embodying the invention, such detail construction being but one of various mechanical forms in which the principle of the invention may be used. l

Vln said. annexed drawings-Figure 1 represents a longitudii'ial section of my improved lubricator. Fig. 2 represents a rear ond view of the holder and cap with the chain removed. Fig. 3 represents a rear end view of the holder with the cap removed. Fig. l represents a face view of the cap. Fig. 5 represents an axial section of the cap. Similar numerals of reference indicate correspoiuling parts in the figures.

Referring to the drawings, the refeience numeral 1 indicates the barrel of the lubricant holder. having the stem, 2, by means of which the device is supported in proximity to the wheel, as disclosed in the above named Letters Patent. Said barrel is preferably rectangular in crosssection, such being usually the shape of the bar or stick of lubricant used in these devices. At the rear end of the barrel is an enlarged cylindrical chamber, forming a shoulder, 1, and having a number of inwardly projecting flanges or lips, 5, upon its rear edge,-in the present instance, four. A cap, 6, lits in said chamber and has a peripheral flange which is cut away to form notches, 7, adapted to register with and slip inward over the lips upon the edge of the chamber. The outer faces of the tongues, 8, formed by notching the fiange are formed with recesses, 9, cor- Specification of Letters Patent.

face of the cap, or other similar projection l is provided by means of which the cap may be manipulated.. A projecting socket, 12, is formed upon the inner side of the cap. A follower, 13, fits to slide within the bore of the barrel, and has a recess, 14, into which the tenoned end of the stick of lubricant, 15, fits. A coiled spring, 16, bears against said follower and has its rear end confined in the socket ofthe cap. A chain, 17, or similar flexible connection has one end secured to the follower and passes through an openinU, 18, in the cap and is secured with its other end to the latter. A ring, 19, having a pin, 20, is provided for drawing the chain rearward and for adjusting it and the follower, similar to the ring and pin disclosed in the Conniff Patent, No. 1,039,650, above referred to.

In lubricators of this type, as heretofore made, cams or set-screws have generally been employed to secure the cap to the end of the barrel, and, as the lubricator is supported from t-he truck of a car or locomotive, it is subjected to constant vibrations and jolts while in use. Such fastening means have rapidly become loosened with the result that the cap falls out, carrying with it the chain, follower and stick of lubricant. The spring in the present device will hold the lips upon the edges of the chamber in engagement with the recesses in the tongues of the cap, taking up the vibrations and movements from shock. The cap can be removed by pushing it inward and giving it a slight turn,in the illustrated form a one-eighth turn,-when the chain spring and follower can be removed and a new stick of lubricant inserted, and securing of the cap is equally simple. The tension of the follower-spring will, when the lubricant stick bears against the wheel, assist in holding the cap against the lips upon the edge of the chamber and thus the tendency of said spring, in the present device, is to keep the locking means in en- Aso gagement and the cap seatedv` while in former devices this tendency has been the reverse. The inter-engaging and alternately interrupted flange -joint and interlocking projections and depressions with the yielding means for holding the parts in engagement accomplish the present advantage.

Other modes of applying' the yprinciple of my invention may be employed for theL mode herein explained. Change may thereforebe made as regards the mechanism thus disclosed, provided the principles of construction set forth, respectively, in the following claii'rs are employed.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is 1. In a device of the character stated, a lubricant-holder comprising a barrel having a passage therethrough,a follower therein adapted to receive a stick of lubricant, a chamber at the rear end of said barrel having a shoulder formed at the junction of said chamber and passage, lips projecting inwardly from said chamber, a cap fitting in said chamber, interlocking devices common to said cap 'and lips, a spring in said chamber intermediate said shoulder' and said interlocking devices, and a spring intermediate said'follower and said cap.

Q. 'In a device of the character stated, a i

lubricant-holder, a cap for closing the end of thesame, said elements formed with incopies f this patent maybe obtained for ter-engaging and alternately interrupted flange-joint elements having their opposed engaging faces formed with corresponding projections and depressions. and yielding means bearing against said holder and cap to hold such joint-elements in engagement. y 3. In a device of the character stated. a lubricant-holder having a chamber at its rear' end provided with inwardly-projecting spaced lips, a cap iitting in said chamber and formed with notches corresponding 'to said lips and with tongues between such not-ches having recesses in their outer faces corresponding to said lips, and a spring seated in said chamber and bearing against said cap.

Yi. In a device of the character stated. a lubricant-holding barrel. a chamber at the rear end of said barrel provided with inwardly-projecting spaced lips, a follower in said barrel, a cap fitting in said chamber and formed with peripheral notches corresponding to said lips and with tongues between such notches having recesses in their cuter faces corresponding to said lips. a springseated in said chamber and bearing` against 'said cap, and a spring interposed between said follower and cap.
